TMDs in Laguerre polynomial basis
Abstract
We suggest modification of the standard approach to TMDs. The modification consists in the consideration of the small operator product expansion in the different operator basis. Instead of power expansion we suggest to use the Laguerre polynomial expansion. Within such a scheme the first term of OPE saturates TMDs in the wider range of in comparison to the power expansion that decreases the significance of non-perturbative factor at small . The presented modification does not violate any TMD properties and can be used within any formulation of TMD factorization.
